Abstract

A search query for a predefined protocol name for the electronic medical report is generated. The search query is processed for the predefined protocol names. One or more predefined protocol names are identified from a plurality of protocol names in a protocol names database. An electronic medical report is generated using the one or more predefined protocol names. A rank for the protocol names is computed based on best matching criteria. The one or more of the identified predefined protocol names are selected based on the rank associated with the protocol name. The predefined protocol name is assigned to an appropriate field in an electronic medical report. A medical report database storing all the medical reports is indexed based on the predefined protocols so that the medical reports may be searched by querying the predefined protocol name.

Description

BACKGROUND

The present embodiments relate to a method and system for generating electronic medical report. The method and system of the present embodiments may be used for generating electronic medical reports having uniform nomenclature in certain fields.

Currently in the healthcare environment, the diagnostic imaging field is heading towards standardization. When a patient is scheduled for an imaging examination, an imaging report is generated after the imaging examination is executed. The imaging exam may be conducted using various modalities such as X-ray, computerized tomography, magnetic resonance imaging and the like. Typically, when a patient is scheduled for an exam, the technicians provide the basic information such as, patient name, date of birth, scan type, and protocol used, required by the medical imaging modalities. Once the scanning is completed, all the data entered by the technician is recorded in Radiation Dosage Structured Report (RDSR) or images. The dosage information may be recorded in the RDSR by the imaging modality or the technician. Protocol name is one of the important fields in the RDSR, as the protocol name is useful at the time of auditing. Protocol name may be based on parameters such as body region, modality type, laterality, anatomic focus and the like. Generally, the technicians enter informal names as protocol names, which do not relate to any of the aforementioned parameters. In some cases, the protocol names may not include the required information such as body regions or anatomical region. Further, such informal naming practices lead to non-standardized naming practices across healthcare institutions. As a result, it is difficult to establish national registry, such as a radiation dosage national registry, to facilitate comparisons among different types of procedures using different medical imaging modalities across various healthcare institutions.

There are efforts to bridge this inconsistency by introducing uniformity in protocol names that are furnished in the RDSR. Organizations such as Radiological Society of North America (RSNA) are taking active steps in this direction. One of the initiatives RSNA has taken in this regard is the introduction of RadLex Playbook. RadLex Playbook aims to provide a standard system for naming radiology procedures based on the characteristics of a medical imaging exam such as modality or body part. The RadLex Playbook provides a unique RPID for each procedure. The RPIDs are to be entered in the RDSRs for making the naming convention standardized. The use of RPID also results in formation of national dosage registry where the dosage values of various procedures may be compared and improved.

At present, the task of finding out the RPID by a technician during/before the medical imaging procedure is not performed. The RPIDs are mapped to the informal names provided in the RDSRs during auditing. This is a cumbersome and time consuming task.

SUMMARY AND DESCRIPTION

The scope of the present invention is defined solely by the appended claims and is not affected to any degree by the statements within this summary.

There is need for an easier way to include standardized protocol names in the RDSR. The present embodiments may obviate one or more of the drawbacks or limitations in the related art. For example, medical reports that include predefined protocol names are generated. Including predefined protocol names in the medical reports is very beneficial during auditing, as the medical reports will have a standard terminology across healthcare institutions.

A method, a computing device, and a system for generating medical reports that include predefined protocol names are provided. The method and apparatus enables a technician to furnish the relevant predefined protocol names in a medical report before commencing the exam on a patient. The method includes, at act 62, generating a search query for a predefined protocol name for the electronic medical report. In an embodiment, the search query is generated by a user before commencing the imaging examination on the patient. In another embodiment, a computing device determines at least one characteristic of the medical image and automatically generates a search query based on the at least one characteristic of the medical image. For example, the computing device may determine characteristics of a medical image such as body region, modality type, and exam type from an appointment schedule. Based on this information, the computing device may generate a search query for a predefined protocol name based on the characteristics of the medical image. The search query for the predefined protocol names is processed. The search query is processed by extracting keywords that indicate a characteristic of a medical image. Thereafter, one or more analogous terms corresponding to the keywords are determined using a medical dictionary database. Further, a search phrase is generated based on the one or more analogous terms.

One or more predefined protocol names are identified from a plurality of protocol names in a protocol names database. The predefined protocol names are identified by comparing the analogous terms in the search phrase with one or more medical dictionary terms in the protocol names database. For the purpose of selecting the predefined protocol names, the protocol names database is indexed based on the medical dictionary terms that are present the medical dictionary database 38. Thereafter, one or more predefined protocol names corresponding to the matching terms are retrieved from the protocol names database.

A rank for the protocol names is computed based on best matching criteria. For example, the best matching criteria may be a relevance of the search phrase with the medical dictionary terms and the number of terms in the search phrase matching with indexed medical dictionary terms.

Thereafter, one or more of the identified predefined protocol names are selected based on the rank associated with the protocol name. The predefined protocol names may be selected manually by the technician operating the imaging modality. An electronic medical report is generated using the one or more predefined protocol names.

The server 32 includes the memory 4, which includes a search query generation module 6, a protocol name identification module 8, and a report generation module 10. The server 32 is configured to accept search queries from the client devices 36.1-36.N. The protocol name identification module 8 is configured for processing the search query for the predefined protocol name. In detail, the search query is processed by extracting keywords from the search query. The keywords indicate a characteristic of a medical image. The characteristics of a medical image may include, but are not limited to, a body region, examination type, modality type, and protocol description. Based on these terms, the protocol name identification module 8 is configured to determine one or more analogous terms corresponding to the keywords using a medical dictionary database. The medical dictionary database 38 includes analogous or equivalent terms for every term related to the medical or diagnostic field. The medical dictionary database 38 may be indexed based on the terms used in the medicine or diagnostics field. The protocol name identification module 8 retrieves one or more analogous terms for every term in the search query. Thereafter, the protocol name identification module 8 is configured to generate a search phrase based on the one or more analogous terms. The search phrase is used for searching a protocol names database 40 for retrieving relevant predefined protocol names for use in the medical report. In an embodiment, the protocol names database 40 is indexed by associating a medical dictionary term with appropriate predefined protocol names. The server 32 may compute a rank for the protocol names based on best matching criteria. The best matching criteria may include a relevance score associated with the predefined protocol name. Further, the server 32 is configured to select the one or more of the identified predefined protocol names based on the rank associated with the protocol name. The selected predefined protocol name is assigned to a medical report. In an embodiment, the medical report is a Radiation Dosage Structured Report (RDSR). The medical report is rendered searchable using the predefined protocol names. This feature is very helpful during radiation dosage auditing sessions.

FIG. 3 illustrates an exemplary diagram of an apparatus 50 for generating medical reports, in accordance with an embodiment in which the server 32 may receive a search query from an imaging modality 48 for searching medical reports based on the predefined protocol names. Once the search query is received, the electronic medical report repository is searched based on the terms in search query. The search query includes a predefined protocol name.

In an embodiment, the apparatus 50 is set up in a cloud computing environment. In such an embodiment, the medical dictionary database 38 and the protocol names database 40 is set up in a cloud environment. The medical dictionary database 38 and the protocol names database 40 are appropriately indexed based on the medical terms. The client devices 36.1-36.N may generate a search query for a predefined protocol name. In an example, the search query is generated by an imaging modality. In another embodiment, the search query may be generated by a technician using the imaging modality. The search query may contain one or more search terms associated with body region, modality type, laterality, population, contrast type, anatomical focus, and reason for exam. For example, body region may include regions of the body such as head and abdomen. Further, laterality may include terms such as bilateral, left, or right. Reason for exam may include, for example, stroke, screw replacement, and trauma. Anatomical focus may include terms such as, but not limited to, pancreas, pulmonary arteries, mandible and coronary arteries.

For example, the technician may type

- Body region: Head
- Modality Type: CT
- Population: Child
- Reason for exam: Trauma

The search query is then processed by the server 32. The server 32 extracts analogous or equivalent terms from the medical dictionary database 38, which is deployed in the cloud environment. The server 32 generates a search phrase that includes the search terms along with the analogous terms extracted from the medical dictionary database 38. For example, the search phrase generated by the server 32 may be as below:

- Search Phrase: (Head OR Cranium) AND (Computerized Tomography OR CT) AND (Child OR Pediatric) AND (trauma)

The search phrase is used to search the protocol names database 40 for a best matching predefined protocol name to be inserted in the medical report. The protocol names database 40 is indexed based on the terms of the medical dictionary. In an exemplary embodiment, the predefined protocol names in the protocol names database 40 may be indexed using Lucene free-text search engine. Accordingly, the terms of the search phrase are matched with the indexed terms of protocol names database 40, and a set of predefined protocol names are shortlisted. Some exemplary protocol names and the corresponding best matching score are as given in Table 1.

	TABLE 1

	Protocol Name	Best Matching score

	PID_3016	6.25
	PID_1124	5.5
	PID_4521	4.3

The set of the predefined protocol names are presented in the display unit associated with the imaging modality 48. In an embodiment, the shortlisted predefined protocol names may be ranked based on a best matching score. At the imaging modality 48, the technician may select a relevant predefined protocol name to be included in the report using an input device. In an embodiment, a predefined protocol name from the suggested protocol names may be automatically assigned to an appropriate field in the medical report. For example, the technician may select the predefined protocol name PID_3016. Thereafter, the predefined protocol name PID_3016 may be included in the medical report that is generated after performing the imaging procedure on the subject.

Since the databases are deployed in the cloud environment, the recommendation of predefined protocol names may be provided as a service to all the client devices. The protocol name suggestion service may be provided at a hospital level or regional level. The protocol name suggestion service may be used by all the hospitals to have a uniform protocol name in the medical report. For example, the protocol name suggestion service may be used to have a uniform RadLex Playbook ID (RPID) in the RDSR for a particular imaging procedure.

In another embodiment, the medical reports with the predefined protocol names are stored in the medical reports database 42. The medical report database 42 is further indexed based on the predefined protocol names. This enables a user to search the medical records based on predefined protocol names. This feature facilitates the auditing process, as the auditing firm will be able to peruse all the medical records of a particular category. For example, a radiation dosage auditing firm may retrieve all the medical reports having the predefined protocol name PID_3016 in order to examine all the reports with the criteria of Head (body region), CT modality type, population type child, and reason for examination as trauma.

FIG. 4 illustrates a flow diagram 60 of the method acts involved in generating a medical report, in accordance with an embodiment. At act 62, a search query is generated for a predefined protocol name for the electronic medical report. In an embodiment, the search query is generated by a user before commencing the imaging examination on the patient. In another embodiment, a computing device such as computing device 2 determines at least one characteristic of the medical image and automatically generates a search query based on the at least one characteristic of the medical image. For example, the computing device 2 may determine characteristics of a medical image such as body region, modality type, and exam type from an appointment schedule. Based on this information, the computing device 2 may generate a search query for a predefined protocol name based on the characteristics of the medical image. At act 64, the search query for the predefined protocol names is processed. The search query is processed by extracting keywords that indicate a characteristic of a medical image. Thereafter, one or more analogous terms corresponding to the keywords are determined using a medical dictionary database. A search phrase is generated based on the one or more analogous terms.

At act 66, one or more predefined protocol names are identified from a plurality of protocol names in a protocol names database. The predefined protocol names are identified by comparing the analogous terms in the search phrase with one or more medical dictionary terms in the protocol names database. For the purpose of selecting the predefined protocol names, the protocol names database 40 is indexed based on the medical dictionary terms that are present in the medical dictionary database 38.

Thereafter, one or more predefined protocol names corresponding to the matching terms are retrieved from the protocol names database 40.

At act 68, a rank for the protocol names is computed based on best matching criteria. For example, the best matching criteria may be a relevance of the search phrase with the medical dictionary terms and the number of terms in the search phrase matching with indexed medical dictionary terms.

At act 70, one or more of the identified predefined protocol names are selected based on the rank associated with the protocol name. The predefined protocol names may be selected manually by the technician operating the imaging modality. In another embodiment, the predefined protocol name may be automatically selected based on the rank associated with the predefined protocol name. At act 72, an electronic medical report is generated using the one or more predefined protocol names. Further, the medical reports are rendered searchable using the predefined protocol names. The feature making the medical reports searchable by predefined protocol name is very beneficial during auditing.

The embodiments enable standardization of naming conventions at institutional levels. The need for mapping informal protocol names to standardized names is eliminated, which saves both time and resources. The embodiments enable standardizing the naming convention and mapping the medical records based on the naming convention at a single instance. The protocol name suggestion service based on the embodiments disclosed herein enables the hospitals across the globe to have uniform protocol names for the medical reports such as RDSR. The protocol name suggestion service may be made a part of the workflow of imaging examinations, which speeds up the process of auditing the medical reports such as RDSRs.
